Taw qhia
Iav Fiber Reinforced Polycarbonate(GFRPC) tau tshwm sim los ua tus thawj coj hauv thaj tsam ntawm cov ntaub ntawv ua tau zoo, ua rau kev lag luam ntxim nyiam nrog nws lub zog tshwj xeeb, ua haujlwm ntev, thiab pob tshab.Nkag siab txog cov ntsiab lus thiab kev sib txuas ntawm GFRPC yog qhov tseem ceeb rau kev txaus siab rau nws cov khoom zoo kawg thiab ntau yam kev siv.
Txhais iav Fiber Reinforced Polycarbonate (GFRPC)
Iav Fiber Reinforced Polycarbonate (GFRPC) yog cov khoom siv sib xyaw uas sib xyaw ua ke lub zog thiab tawv tawv ntawm iav fibers nrog cov ductility thiab pob tshab ntawm polycarbonate resin.Qhov kev sib koom ua ke ntawm cov khoom no ua rau GFRPC nrog cov txheej txheem tshwj xeeb uas ua rau nws yog cov khoom siv zoo heev rau kev siv ntau yam.
Tshawb nrhiav kev sib txuas ntawm iav Fiber Reinforced Polycarbonate (GFRPC)
Lub synthesis ntawm iav Fiber Reinforced Polycarbonate (GFRPC) koom nrog cov txheej txheem ntau kauj ruam uas ua tib zoo sib xyaw cov iav fibers rau hauv polycarbonate matrix.
1. Kev npaj iav Fiber:
Cov iav fibers, cov khoom siv txhawb zog ntawm GFRPC, feem ntau yog tsim los ntawm cov xuab zeb silica, cov khoom siv ntuj tsim muaj nyob hauv lub ntiaj teb cov pob zeb.Cov xuab zeb yog thawj zaug purified thiab melted ntawm qhov kub thiab txias, nyob ib ncig ntawm 1700 ° C, los tsim ib lub iav molten.Cov iav molten no raug yuam los ntawm cov nozzles zoo, tsim cov iav fiber ntau nyias.
Txoj kab uas hla ntawm cov iav fibers tuaj yeem sib txawv raws li qhov xav tau ntawm daim ntawv thov.Rau GFRPC, fibers feem ntau yog nyob rau hauv thaj tsam ntawm 3 mus rau 15 micrometers inch.Txhawm rau txhim kho lawv cov adhesion rau polymer matrix, iav fibers tau kho qhov chaw.Qhov kev kho no suav nrog kev siv tus neeg sawv cev sib txuas, xws li silane, mus rau qhov chaw fiber ntau.Tus neeg sawv cev sib txuas tsim cov tshuaj sib txuas ntawm cov iav fibers thiab cov polymer matrix, txhim kho kev ntxhov siab thiab kev ua tau zoo tag nrho.
2. Kev npaj Matrix:
Cov khoom siv matrix hauv GFRPC yog polycarbonate, thermoplastic polymer paub txog nws cov pob tshab, lub zog, thiab kev cuam tshuam.Polycarbonate yog tsim los ntawm cov tshuaj tiv thaiv polymerization uas muaj ob lub ntsiab monomers: bisphenol A (BPA) thiab phosgene (COCl2).
Cov tshuaj tiv thaiv polymerization feem ntau yog ua nyob rau hauv ib puag ncig tswj kev siv lub catalyst kom ceev cov txheej txheem.Cov txiaj ntsig polycarbonate resin yog cov kua nplaum uas muaj qhov hnyav molecular.Cov khoom ntawm polycarbonate resin, xws li qhov hnyav molecular thiab cov saw ntev, tuaj yeem raug kho los ntawm kev kho cov tshuaj tiv thaiv kab mob thiab catalyst system.
3. Kev sib xyaw thiab kev sib xyaw:
Cov iav fibers npaj thiab polycarbonate resin raug coj los ua ke hauv cov kauj ruam sib xyaw.Qhov no suav nrog kev sib xyaw ua ke siv cov tswv yim xws li ntxaib-ntsia hlau extrusion kom ua tiav cov kev sib cais ntawm cov fibers hauv matrix.Kev faib tawm ntawm fibers cuam tshuam rau qhov kawg ntawm cov khoom sib xyaw.
Twin-screw extrusion yog ib txoj hauv kev rau kev sib xyaw GFRPC.Nyob rau hauv cov txheej txheem no, cov iav fibers thiab polycarbonate resin yog pub rau hauv ib tug ntxaib-ntsia hlau extruder, qhov chaw uas lawv raug rau mechanical shearing thiab tshav kub.Lub zog shearing rhuav tshem cov pob khoom ntawm cov iav fibers, faib lawv sib npaug hauv cov resin.Thaum tshav kub kub pab kom soften cov resin, cia kom zoo fiber ntau dispersion thiab matrix txaus.
4. Moulding:
Lub compounded GFRPC sib tov yog ces molded rau hauv cov duab uas xav tau los ntawm ntau yam txuj ci, nrog rau kev txhaj tshuaj molding, compression molding, thiab ntawv extrusion.Cov txheej txheem molding tsis, xws li kub, siab, thiab txias npaum li cas, ho cuam tshuam cov khoom kawg ntawm cov khoom, cuam tshuam cov yam xws li fiber ntau orientation thiab crystallinity.
Kev txhaj tshuaj molding yog cov txheej txheem siv dav siv los tsim cov khoom siv GFRPC nyuaj nrog qhov raug siab.Nyob rau hauv cov txheej txheem no, molten GFRPC sib tov yog txhaj nyob rau hauv lub siab siab mus rau hauv lub kaw pwm kab noj hniav.Cov pwm yog txias, ua rau cov khoom ua kom khov thiab coj cov pwm pwm.
Compression molding yog tsim los ua cov khoom tiaj tus lossis yooj yim-puab GFRPC Cheebtsam.Hauv cov txheej txheem no, GFRPC sib tov yog muab tso rau ntawm ob lub puab tsaig thiab raug rau kev kub siab thiab kub.Cov cua sov ua rau cov khoom muag muag thiab ntws, sau cov pwm kab noj hniav.Lub siab compacts cov khoom, xyuas kom meej uniform ntom thiab fiber tis.
Sheet extrusion yog siv los tsim cov nplooj ntawv GFRPC txuas ntxiv.Nyob rau hauv cov txheej txheem no, molten GFRPC sib tov yog yuam los ntawm ib tug slit tuag, tsim ib daim ntawv nyias ntawm cov khoom.Cov ntawv yog tom qab ntawd txias thiab dhau los ntawm cov yob los tswj nws cov thickness thiab cov khoom.
5. Tom qab ua tiav:
Nyob ntawm daim ntawv thov tshwj xeeb, GFRPC cov khoom yuav raug kho tom qab ua tiav, xws li annealing, machining, thiab nto tiav, txhawm rau txhim kho lawv cov kev ua tau zoo thiab kev zoo nkauj.
Annealing yog txheej txheem kev kho cua sov uas yuav maj mam ua kom sov cov khoom GFRPC mus rau qhov kub thiab txias thiab maj mam txias.Cov txheej txheem no yuav pab txo qis kev ntxhov siab nyob rau hauv cov khoom, txhim kho nws cov toughness thiab ductility.
Machining yog siv los tsim cov duab meej thiab cov yam ntxwv hauv GFRPC cov khoom.Ntau cov txheej txheem machining, xws li milling, tig, thiab drilling, tuaj yeem ua haujlwm kom ua tiav qhov ntev thiab siab ntev.
Kev kho deg tiav tuaj yeem txhim kho qhov tsos thiab ua haujlwm ntev ntawm GFRPC cov khoom.Cov kev kho no yuav suav nrog kev pleev xim, plating, lossis siv cov txheej tiv thaiv.
